XSL evaluating variables doesn't work correctly (as i wish it to ;))
Please have a look and tell me wether what i'm trying to do is impossible or if i'm just using wrong means...
my problem is that:
Code:
<xsl:if test="$search != ''">
<xsl:for-each select="database/computer[$search = $searchparam]">
if i write the following line it works:
Code:
<xsl:for-each select="database/computer[@owner = $searchparam]">
now i wonder: why does using with a variable work in xsl:if but if i try to use it on the left side of xsl:for-each it doesn't?
Attachments:
this is an excerpt from my xml-file:
Code:
<database>
<computer id="1" owner="zyrill" hostname="" update="2003/5/19">
<hardware>
<case>Desktop</case>
<cpu>
<name speed="700">Athlon</name>
</cpu>
<harddisc>
<name size="17.1">Quantum Atlas 10K 18WLS SCSI</name>
</harddisc>
<ram type="SDR">128</ram>
<drives>
<name type="CD">Plextor PX-12TS SCSI</name>
</drives>
<monitor>Step</monitor>
<printer></printer>
<scanner></scanner>
<etc>
<name></name>
</etc>
</hardware>
<software>
<os>Win2K</os>
<application>
<name>Office 2000</name>
<name>SilkRadar</name>
<name>TightVNC</name>
<name>VirusScan</name>
</application>
</software>
</computer>
</database>
and this is the xsl-file i'm using to render it:
Code:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes" encoding="ISO-8859-1" doctype-public="-//w3c//dtd html 4.0 transitional//en" />
<xsl:param name="search">@owner</xsl:param>
<xsl:param name="searchparam">krueger</xsl:param>
<xsl:param name="sort"></xsl:param>
<xsl:template match="/">
<html>
<head>

well now - THIS is the php used to convert the xml using xsl to xhtml on the server:
PHP Code:
<?php
if ($_POST["submit"])
{
if (isset($_POST["search"]))
{
$search = $_POST["search"];
}
else
{
$search = 'nil';
}
if ((isset($_POST["searchparam"])) and ($_POST["searchparam"] != ''))
{
$searchparam = $_POST["searchparam"];
}
else
{
$searchparam = 'nil';
}
if (isset($_POST["sort"]))
{
$sort = $_POST["sort"];
}
else
{
$sort = 'nil';
}
}
$xmlfile = 'computers.xml';
$xslfile = 'sort.xsl';
$xh = xslt_create();
$arguments = array ( 'foo' => 'bar' );
$parameters = array (
'search' => $search,
'searchparam' => $searchparam,
'sort' => $sort );
$result = xslt_process($xh, $xmlfile, $xslfile, NULL, $arguments, $parameters);
if ($result) {
print $result;
}
else {
print "Either <font color='#0000FF'>$xmlfile</font> or <font color='#0000FF'>$xslfile</font> seems to be erratic.";
print "<br>Following error occured while trying to perform the tranformation: <font color='#FF0000'>" . xslt_error($xh) .
print "</font><br>The error code is <font color='#FF0000'>" . xslt_errno($xh) . "</font>";
}
xslt_free($xh);
?>
